Coated micronized calcium carbonate powders are covered with a layer of stearic acid, a type of fatty acid, and are regarded as appropriate alternatives for polymeric raw materials in the production process. 

Usages of coated calcium carbonate have many advantages in plastic and coating. Day by day, more these processors are shifting to coated grades due to:

• Low surface energy
• High Hydrophobic effect, to get easy and homogeneous dispersion 
• Low oil  ,  DOP and polymer absorption.
• Increase in mechanical strength, to get high quality surface and high brightness.
• Adaptation  to  organic  Environments.
